GAGE SYSTEM FOR FIRE-ENGINES.

Application filed July 8, 1919/ Serial No. 309,489. v

To all whom it may concern."

Be it known that I, ALBERT B. HOUSE, a citizen of the United States, residing in the bore-ugh of Brooklyn of the city of New York, in the State of New York, have invented certain new and useful Imlprovements in Gage Systemsfor Fire-Eng1nes, of

' reference being had to the accompanying drawing, forming a part hereof.

This invention relates to an improved gage system adapted particularly for motor fire engines in accordance with which the gage or gages and their pipe connections with the water lines leading to or from the fire pump are protected against possible freezing by water jackets supplied with warm water from the jacket of the propelling motor. For convenience in this application the gages for both the inlet and outlet sides of the fire pump are shown mounted on a single member provided with 'separate water chambers therein and the pressure gage on the outlet side of the pump has its water connections jacketed and supplied with warm water from the circulatory system of the propelling motor.

The invention will be described in connection with this embodiment as shown in the accompanying drawing, in which- Figure 1 is a view in side elevation of a portion of a motor fire engine provided with the improved gage system. V

Fig. 2 is a fragmentary view, partly in section and partly in elevation, showing in detail the applicationof the improved gage system to the water lines of a fire pump.

The motor truck a may be propelled by a fire pumpindicated conventionally at c,

in a manner now commonly known. The. inlet side of the pump is represented by the connection d and the outlet side by the line? e. It is desirable to provide one or both of the 1ines'd, e, with gages f, g, respectively, for the purpose of permitting the pressures therein to be determined by the attendant. Inaccordance with the illustrated embqlfimentthese gases f, g are mounted on a s' gle support It chambered as at a, k, the chamwith the inlet line through a channel 5' and with the gage 7 through a channel 5 and the gage communicating-with the outlet line e rough gage g and the discharge pipe e, but oper-' able to subject the gage momentarily to the pressure in the discharge line e for a readmg The discharge line 6 is formed with a port e which communicates with the port is through a pipe n. It i the pipe connections of this character which, associated with one or more gages in the fire engine, are subject to freezing. It is the principal object of this invention to protect a connection, such as the connectionn by means of warm water derived from the circulatory system of the propelling motor 6. In the illustrated embodiment such a jacket, surrounding the pipe n, is indicated by the reference character 0, and this jacket" is connected through the circulatory system of the motor 6 by means of a pipe p in which may "be disposed a hand valve pv to permit the jacket 0 to be shut off from the circulatory system of the motor when war-In water is not required in the jacket. In the illustrated embodiment the pipe ;0 communicates directly with the jacket of one of the cylinders of the motor 6, but it is evident that the connection might be effected at any other part of the circulatory system. Drain cocks n, 0 may be placed at the lower levels of the pipe n and the jacket 0, respectively, to permit all of the water to be drained from the gage system when the latter is not in general user e The important feature of the invention aside from the particular embodiment illustrated resides in the use of the water in the circulatory system of the motor I) which is warm for the purpose of protecting one or more of the gages and the connections therefor which might be employed in a motor pipes, a jacket for the connection, and a con- ,nection between the jacket and the circulation with the motor and circulatory system therefor, fire pump, inlet and discharge pipes therefor, of a gage and chambered support on which the vgage is mounted, connections between the chambered support and the gage and between the chambered support and one of saidpipes, a jacket for the last named connection and a connection between the jacket and said circulatory system.

3. In a. motor fire engine, the combination with the motor and water jacket therefor,

fire ump, inlet and discharge pipes there a connection, a connection between the jacket and said first named "jacket, and drain cocks in the second named jacket and the connection between-the chambered support and 25 said pipe from the fire pump.

This specification signed this 30th day of June, A. 1). 1-919.
